[QUOTE="mikegett, post: 1582421, member: 561005"] It could be a couple of issues. Any where that metal makes contact and heat is added, corrossion will form. Think of your battery terminals. It mainly has to do with the composition of the metal oxidizing. Lead is used on most soldered joints and will oxidize at higher temps. Parts used in cars tend to have a protective coating in the soldering process to prevent this. It is possible that your parts are oxidizing due to a poor solder joint. The poor joint will cause more resistance and more heat to pass through it. The other possibility is that it is not oxidation. Your capacitor can tend to fail and leak a lime like substance. Your amp will still work but have intermittant failures. Do you see any signs of the capacitors leaking? [/QUOTE]
